Posted on April 18, 2016 at 21:49Hello, EVAL6480H uses very robust MOSFETs with hefty intrinsic diodes (25A pulsed current). Does this suggest that it would be ok in practice to exclude catch/snubber diodes from H-bridge design when employing the L6...
Posted on March 17, 2016 at 11:26Dear all,we are noticing breakdown of SPV1040 in our implementation on a board for energy harvesting from solar panel. The breakdown is only for some board. Here you can see the configuration.The solar panel is a cou...

Posted on April 13, 2016 at 16:52Hi, I'm using PM8800A in isolated topologies, 5 Vout with synchronous rectification. I followed the directions of Application notes AN_2783 and used the STS26N33LLH6 transistor output from the transformer. The proble...
Posted on March 30, 2016 at 20:21 Anyone had any luck getting the example project compiled and running for the Nucleo-IHM001? The binaries work fine respectively in both 6step and FOC modes. However when the example provided with SPN7V1.0.0 is c...
Posted on November 12, 2015 at 21:17When I send any get or set command from micro to L6470 via SPI, the L6470 always responds with the command byte sent by the micro. It should be either sending the MSB of the get data or a 0 byte for a set command ...
Posted on April 13, 2016 at 11:48Hello, I am using the eval board EVAL6226QR that has the dual full bridge driver L6226Q on it. I am using it to drive a 40kHz train of pulses from IN1A to OUT1A (and IN2A to OUT2A). To minimize current consumption, I...
Posted on April 13, 2016 at 11:27Hallo..I am using L6205 in parallel connection mode for high current. I have attached a load resistance of 10ohm at output and the Supply voltage is 12 volt. The load resistance was drawing about 1.2Amp current and I...
